Homeowners typically pay for a new furnace and air conditioner based on system efficiency, size, and installation complexity. Main cost drivers include equipment efficiency, ductwork needs, labor, and permitting. This article presents clear price ranges to help budget decisions and captures regional differences, hidden fees, and practical savings.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Furnace (gas or electric) | $2,000 | $4,000 | $7,000 | Includes unit and basic installation; efficiency varies |
| Air Conditioner (central) | $3,000 | $5,500 | $9,500 | SEER rating and size influence cost |
| Heat Pump (hybrid/system) | $4,500 | $7,500 | $12,000 | Two-stage or variable-speed add cost |
| Ductwork modifications | $1,000 | $3,500 | $6,000 | Includes sealing and insulation |
| Labor & installation | $1,500 | $3,500 | $6,000 | Labor hours depend on home layout |
| Permits & inspections | $100 | $500 | $1,500 | City or county requirements vary |
| Delivery/Removal of old equipment | $100 | $400 | $1,000 | Includes haul-away where required |
| Tax & miscellaneous | $150 | $600 | $1,500 | Sales tax and small add-ons |
Overview Of Costs
Typical cost ranges for a complete new furnace and central AC installation fall between $7,500 and $15,000 for most homes, including equipment, labor, and basic ductwork. In markets with high demand or challenging installs, totals can exceed $20,000. The low end covers entry-level equipment and standard labor, while the high end reflects premium equipment, complex ductwork, and required permits. For a standard 2-3 ton system in a mid-range home, expect about $9,000-$12,000 all-in.
Per-unit pricing commonly appears as $/ton for cooling capacity and $/k BTU or $/SEER for efficiency. A typical 3-ton gas furnace with a 2.5-3 ton AC might show $2,500-$4,000 for the furnace and $3,500-$6,000 for the AC, with combined systems often delivered as a bundled price discount.
Cost Breakdown
Breakdown emphasizes how costs accumulate across components and services. The following table summarizes common cost categories with assumptions and typical ranges.
| Category | Low | Average | High | Assumptions |
|---|---|---|---|---|
| Materials | $3,000 | $6,000 | $11,000 | Furnace + AC unit; efficiency varies |
| Labor | $1,500 | $3,500 | $6,000 | Crew size and complexity of install |
| Equipment | $2,000 | $4,500 | $7,500 | Compressor, furnace, air handler |
| Permits | $100 | $500 | $1,500 | Local permitting rules |
| Delivery/Disposal | $100 | $400 | $1,000 | Haul-away of old unit; freight |
| Warranty | $0 | $300 | $900 | Extended coverage options |
| Contingency | $200 | $800 | $2,000 | Unexpected duct or wiring needs |
| Taxes | $150 | $600 | $1,500 | State and local tax |
What Drives Price
Efficiency and size are the primary price influencers. A higher SEER rating reduces energy use but increases upfront cost. System size, measured in tons, must match the home’s heat load; oversizing or undersizing raises upfront and operating costs. The home’s ductwork condition, insulation, and existing vents also affect installation time and price. In regions with extreme summers or winters, equipment with higher efficiency and variable-speed operation tends to be more common and thus more expensive.
Labor, Hours & Rates
Labor costs vary by region and job complexity. A straightforward replacement in a single-room addition is cheaper than a whole-house retrofit with extensive ductwork. Typical hourly rates range from $75 to $150, with total labor often constituting a sizable portion of the bill. Projects requiring permits or rewiring can add 10–30% to labor charges.
Regional Price Differences
Prices differ across the U.S. due to market demand, labor costs, and permitting fees. In the Northeast and West, bundled installations tend to be higher, while the Midwest and South offer mid-range pricing. For example, a three-bedroom home in a suburban market may see a total of $9,000-$13,000, while rural areas could fall in the $7,500-$11,000 range, and urban centers may approach $12,000-$18,000 or more when premiums apply.
Additional & Hidden Costs
Hidden costs can appear late in the process. Duct cleaning, refrigerant charge, mold remediation, or structural modifications add to the total. If the existing furnace is gas and the new system is electric, electrical service upgrades may be needed. Some homes require new gas lines, or condenser relocation due to landscaping or clearance issues. Budget a 5–15% contingency to cover these items.
Real-World Pricing Examples
Basic Scenario
Specs: 2-ton gas furnace, 1.5-ton AC, standard ductwork, mid-grade thermostat. Installed in a single-story home with reachable equipment closet. Assumes typical permits and standard labor.
Labor hours: 12–16; Total: $7,800-$9,200. Equipment: $5,000; Materials and permits: $1,800; Taxes and disposal: $700. Assumptions: region, specs, labor hours.
Mid-Range Scenario
Specs: 3-ton gas furnace, 2.5-ton AC, enhanced filtration, mid-range SEER, modest duct upgrades. Includes basic humidity control and a smart thermostat.

Savings Playbook
To reduce upfront costs, consider standard equipment with fewer bells and whistles and compare bundled quotes from multiple contractors. Look for rebates, seasonal promotions, and manufacturer financing. If energy costs are a concern, a mid-range SEER with good variable-speed operation may offer a favorable payback period versus a basic unit with lower efficiency.
Prices By Region
Regional deltas typically fall within ±15% of the national average for most mid-range setups. Urban regions may add 10–20% due to higher labor and permitting fees, while rural areas can be 5–15% lower. Suburban markets usually align with national averages but can skew higher if the home requires substantial ductwork or system zoning.
